Coal Fire and Spontaneous Combustion Prevention


FLAME-OUT is a formulated fire retardant developed by Reynolds Soil Technologies for extinguishing coal fires and used as a preventative against spontaneous combustion in stockpiles.

FLAME-OUT comes in two forms:

  1. White crystalline powder which is readily soluble in water
  2. Ready to use liquid

FLAME-OUT has been specifically designed and formulated for rapid penetration of the fire retarding chemistry that activates when heated.

Once activated, FLAME-OUT builds up a char layer on burning substrates, smothering the material and inhibiting the oxygen supply, thereby providing a barrier against the heat source or already ignited flame from another source. This charring is virtually instantaneous and will occur whenever FLAME-OUT exists within the stockpile and the combustion process starts.


Powder -

FLAME-OUT powder is readily soluble.

FLAME-OUT can be introduced directly into tankers but ensure the powder is added reasonably slowly with plenty of water agitation e.g. slowly add the powder to a high pressure hose system.

Liquid -

Easily added to water carts directly using a RST supplied pump if required or injected into irrigation lines.

Simply dilute or add FLAME-OUT into a water cart or suitable watering equipment and spray directly over the coal fire or spray over the stockpile as it is being laid up.

A corrosion inhibitor is also contained in the product to help protect machinery however it is important to flush out thoroughly (water tanks, pumps, plumbing & hoses) at the end of each days usage with clean water.
